{"product_id":"sparkfun-rtk-surveyor","title":"SparkFun RTK Surveyor","description":"\u003cp\u003eThe SparkFun RTK Surveyor is an easy to use GNSS receiver for centimeter-level positioning. Perfect for surveying, this preprogrammed device can also be used for autonomous driving, navigation, asset tracking and any other application where there is a clear view of the sky. The RTK Surveyor can also be used as a base station. With the flick of a switch, two RTK Surveyors can be used to create an RTK system capable of 14mm horizontal positional accuracy. The built-in Bluetooth�® connection via an ESP32 WROOM enables the user to use the RTK Surveyor with their choice of GIS application on a phone or tablet. The built in battery allows field use for up to four hours and is compatible with common USB battery banks.\u003c\/p\u003e \u003cp\u003eThis device can be used in four modes:\u003c\/p\u003e \u003cul\u003e \u003cli\u003eGNSS Positioning (~30cm accuracy)\u003c\/li\u003e \u003cli\u003eGNSS Positioning with RTK (1.4cm accuracy)\u003c\/li\u003e \u003cli\u003eGNSS Base Station\u003c\/li\u003e \u003cli\u003eGNSS Base Station NTRIP Server\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eIn \u003cstrong\u003ePosition\u003c\/strong\u003e mode the device receives L1\/L2 signals from a user-provided antenna and the high-grade GNSS receiver provides lat\/long and altitude with accuracies around 300mm.\u003c\/p\u003e \u003cp\u003eIn \u003cstrong\u003ePositioning with RTK\u003c\/strong\u003e mode the device receives L1\/L2 signals from the antenna and correction data from a base station.

This type of base is a very easy way to setup a very precise absolute correction source.\u003c\/p\u003e \u003cp\u003eTwo cables are provided with the RTK Surveyor allowing a user to plug on our easy to use \u003ca href=\"https:\/\/www.sparkfun.com\/products\/17255\"\u003eSerial Telemetry Radios\u003c\/a\u003e or their own radio link.
